Quick-Release Fastener Pull Cord Detachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick-release fastener systems for articles of clothing, such as vests and cummerbunds, lack a convenient and efficient mechanism for selective detachment, often requiring complex designs or multiple components.
Innovation Solution
A quick-release fastening system incorporating a pull cord with a peelable and fixed portion, where the pull cord's peelable end supports the quick-release fastener, allowing for easy detachment by applying a pulling force to the handle end, thereby simplifying the release mechanism and reducing component complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional quick-release fastener system is used, then the fastening function is achieved, but the detachment mechanism becomes complex and requires multiple components
Solution Approach 1:
The patent combines the pull cord and quick-release fastener into a single integrated unit. The pull cord's peelable end is directly attached to the peelable portion of the fastener, eliminating the need for separate detachment mechanisms and reducing overall component count while maintaining quick-release functionality
Solution Approach 2:
The pull cord serves multiple functions: it acts as both a drawing mechanism to close the article of clothing and as the activation mechanism for quick-release detachment. By pulling the handle end, the user can both tighten the garment and, by peeling the end, trigger the fastener release, consolidating multiple operations into one component
2Device complexity
If a simple fastener design is used, then the component count is reduced, but the selective detachment capability is lost
Solution Approach 1:
The fastener transitions from a static connection to a dynamic, controllable connection. The peelable portion can be selectively engaged or disengaged by applying force to the pull cord's handle end, allowing the user to control when detachment occurs while maintaining structural simplicity

AI summary
A system includes an article of clothing, a pull cord, and a quick-release fastener. The article of clothing defines a shoulder region having a conduit. The pull cord is movably-supported upon the shoulder region. The quick-release fastener includes a peelable portion directly connected to a peelable end of the pull cord and a fixed portion directly connected to the shoulder region of the article of clothing. Another system includes a vest having a shoulder region and a waist region. A first quick-release assembly is arranged upon the shoulder region of the vest, and a second quick-release assembly arranged upon the waist region of the vest.
